SOUND RECORDING AND REPRODUCING INSTRUMENT.

SPECIFICATION forming part of Letters Patent No. 600,315, dated March 8, 1898.

Application filed March 13,1897. Serial No. 627,276. (No model.)

To all whom it may concern.-

Be it known that I, JOSEPH IV. JONES, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Sound Recording and Reproducing Instruments; and I do declare the following to be a full, clear, and exact description of the invention, such as will en able others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to new and useful improvements in sound recording and reproducing instruments, especially that class of instruments known as gramophones, and has for its object to provide a simple automatic device having for its motive power a spring which is caused to operate by the insertion of a coin into the coin-chute of the machine, as shown in the drawings and more fully described hereinafter.

In the accompanying drawings, Figure 1 illustrates an end elevation, partly in section, of an instrument embodying the principle of my invention. Fig. 2 is a sectional view on the line 2 2 of Fig. 1, the top cover being removed and the standard supporting the instrument being omitted. Fig. 3 is a plan View of Fig. 2. Fig. 4 is a section on the line 4 4 of Fig. 2. Fig. 5 is a detached sectional View on the line 5 5 of Fig. 6. Fig. 6 is a detached sectional view on the line 6 6 of Fig. 7. Fig. 7 is a section on the line 7 7 of Fig. 6, and Fig. 8 is a detached perspective View of the mechanism controlled by a coin for starting and stopping the instrument.

Similar letters of reference refer to similar parts throughout the drawings.

A is the record, in the form of a disk having upon its face a layer of wax or other like material upon which sound-waves have been recorded.

B is a rotatable table carrying the record, the same being held in position by a thumbscrew B. The shaft 0, which supports said table, has suitable hearings in the framework D of the motor, and motion is imparted to said shaft as follows:

Abeveled pinion E on the shaft 0 engages a beveled gear E, loosely supported upon the shaft E On the same shaft is loosely hung a pinion E connected by a sleeve to the beveled gear E, which meshes with a gear-wheel E fixed to a shaft E and upon this same shaft is fixed a pinion E, which meshes with a gear-wheel E loosely hung to the shaft E The spring E is secured at one end to the shaft E the outer end being connected to the gear-wheel E by a pin e Upon the shaft E is also secured a ratchet-wheel E having a pawl e engaging it, which is pivoted to the framework of the motor. In winding the spring E the shaft E is turned by a crank E (Shown in dotted lines in Fig. 1.)

The sound-box F of the instrument comprises a casing F and ring F, between which is secured the diaphragm F The reduced portion f of the casing is provided with a flexible tube F through which the soundwaves are conveyed to a coupling f in the cover and thence through the tube F to the earpieces.

The stylus or needle G is mounted in a binding-post G, provided with a set-screw G the same being secured to a spring-plate G which is fastened to the sound-box by screws 9 g, the spring-plate G being connected to the diaphragm F by a pin f in the usual manner, and in some cases an additional spring-plate G may be employed, provided with an adjusting-screw g Secured to and forming part of the soundbox is a short arm H, connected to the saddle I by means of screws h h, and in order to provide for a slight irregularity which I find will at times occur between the feed imparted to the saddle and that imparted to the stylus by the record I provide a slot h in the arm 11, in which one of the screws h is free to play.

The saddle I is sleeved at its upper end to a bar J, which bar is supported by uprights K and K, connected to and forming part of base-plate K The saddle I is caused to travel backward and forward upon the bar J by means of two screws L and L. The former, when engaged with the threaded portion of L and L is conveyed from the shaft to the shaft M by means of pulleys O and M, connected by a belt M The shaft M is provided with a worm M which engages the teeth of the worm-wheels L and L secured, respectively, to the ends of the Worms L and L."

The movements given to the saddle and sound-box carried thereby through the arm H are as follows: When the saddle is in the position shown in Figs. 3 and 5, the semithreaded portion I is in engagement with the worm L, which conveys the saddle forward until the same is brought in contact with the cam N, and a further movement compresses the spring n and brings the toothed portion of the cam into contact with a collar 0, which is fixed to the worm-shaft, the same having corresponding teeth which engage the toothed portion of the cam. The cam now turns with the screw-shaft, and a pin 1', projecting from the saddle, is acted upon by the cam and disengages the saddle from the screw L.

Suspended from the bottom of the saddle is a roller P, which when the saddle is in engagement with the screw L rests upon a track or guide Q. As the saddle is disengaged by the cam N from the screw L the roller, which has considerable vertical play uponthe pin which secures it to the saddle, drops by gravity down behind the track or guide Q as the saddle is shifted and holds the saddle and pin Rprojecting therefr0m,into engagement with the quick-return worm L. I V

In order that the pin 1 will properly engage the thread of the screw L when the saddle is shifted, I provide a spring S, which is located in an opening directly back of the pin, so that in case the pin strikes the thread at the moment the saddle is shifted the spring will be compressed until the pin is properly adjusted between the coils of the thread.

As the saddle is moved along by the worm L the roller P is brought in contact with the, inclined plane R, which raises said roller from the track or guide Q, and the weight of ,the sound-box shifts the saddle out of engagement with the worm L and into engagement with the worm L.

The governor T is of the ordinary centrifugal type, comprising the weighted arms T and T connected to the sleeve T by connectinglinks T and T 2. spring S being interposed between the upper pivotal and fixed connection for the arms T and T and the looselysupported flanged sleeve T The shaft T which carries the governor, is driven from the shaft 0 by means of a belt T and pulleys T and T The speed of the machine is regulated by a plate U and thumb-screw M, the former being pivoted at a point it and provided with a pad M, which bears against the flanged portion of the sleeve T to a greater or less extent as the governor revolves, and governs the speed of the device by the frictional contact between said parts.

The coin mechanism for controlling the operation of the instrument embraces a leverV, which is pivoted at a point 21, the weight of said lever and its connecting parts being counterbalanced by a spring S An arm V projects out some distance from the lever V and normally engages a projection 10 on the disk W,which latter is secured to and rotated by the shaft M. Carried by the lever V is abar V acted upon in one direction by a spring S so as to cause one end of the bar to lie in the path taken by the coin in the chute X. When a coin is inserted into the chute X, it passes along until it comes in contact with the projecting end of the bar V the weight of the coin being sufficient to bear down the lever V against the action of the spring S which disengages the arm V from the projection w on the disk W. The instrument being free to operate, the saddle I is fed slowly forward by the screw L, the roller P coming in contact at or near the end of its travel with a lever Y, which, being connected to the lever Y by a small shaft y, operates the bar V against the action of the spring S and releases the coin. The coin being released from the bar V the spring S comes into action and returns the lever V to its normal position; but as the roller V at this point has been carried forward by the bar V in releasing the coin the roller V upon the return of the lever V, comes in contact with a stop V which prevents the arm V from engaging and. locking the disk W until the saddle I has been reversed by the screw L and carried a distance sufficient to I claim, and desire to secure by Letters Pat- 1.
